The Project sprays for mosquitoes using the pesticide, Sumithrin, in a product called Anvil. Sumithrin is a pyrethroid that is classified as slightly toxic by the EPA. Mosquito control applications of Sumithrin do not pose a significant risk to people or their pets due to the low toxicity of Sumithrin and the small amount used to control mosquitoes. As with any pesticide, people should minimize exposure. If residents see a spray truck approaching, they are advised to go indoors for a couple of minutes while the spray dissipates. Residents are also advised to close windows. Beekeepers do not need to take any special precautions since spraying begins after dusk.

The weekly spray schedule can be found on the East Middlesex Mosquito Control Project website at https://sudbury.ma.us/emmcp/. If residents have any questions related to the spraying or any questions on mosquitoes, call the East Middlesex Mosquito Control Project at 781-899-5730.
